Hi NotSoIvory,
I'm not familiar with your situation enough to make an informed contribution but if it is YOUR house and you are just being a good person letting these folks stay at your place I highly suggest you make a plan to rid them from your home. You are not responsible for anyone but you (and children if you have them) and if you cannot find safety in your own home because of people who can go elsewhere you might want to begin thinking about a strategy to make your home the safe place you desire.
Sending good wishes and positive sober thoughts!!
